Abstract
Foxglove aphid (Aulacorthum solani) has become a significant pest in desert lettuce and celery production since its detection in Arizona in 2002. Favoring cool-season crops, FGA causes contamination in harvested produce, especially in lettuce heads and celery hearts. This bulletin summarizes FGA identification, seasonal development, and management practices. Because systemic options are limited, foliar insecticide applications based on action thresholds are critical. Effective management relies on early detection and a preventative spray strategy to minimize marketable losses.
